Title: Casting plant for the continuous centrifugal casting of cylinder liners of internal combustion engines
IPC: B22D13/00

Abstract: 1349300 Centrifugal casting plants and machines REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 15 Nov 1971 [26 Nov 1970] 52872/71 Heading B3F A centrifugal casting plant (Fig. 3) comprises a rotary table 22 carrying a plurality of casting machines, the table 22 presenting each casting machine in turn to a loading/unloading station 31 for chill moulds and a conveyer line 44, 45 for transporting chill moulds between the loading/ unloading station 31 and a casting extracting and removal station 48. Pouring apparatus.-Metal from a tilting furnace 41 is poured sequentially into four ladles 39 mounted on an indexing rotating table 38. The ladles 39 are tilted at a casting station 35 to deliver metal to a pair of chill moulds mounted in centrifugal casting machines via a pair of tundishes 40. The tundishes 40 are movable back and forth radially of the table 38 so that their spouts may enter the mouths of the chill moulds.  Casting machines, clamping and jacketing moulds.-The chill moulds each comprising upper 1 and lower 2 halves are centrifuged in barrels 13 of casting machines (Fig. 1). A core 8 is provided in each mould to define a pricker chamber 9 for waste metal. The chill mould halves 1, 2 are clamped together by rollers 28 mounted between a jacket of angle irons 14 and steel hoops 15. The jacket includes a balancing ring 16 and inertia weights 26 and is rotated by an electric motor 19 via a gearing 20. A sprung table supports the moulds, jacket and motor. After centrifuging, the full chill moulds are removed from the casting machines at station 31 (Fig. 3) by clamps (not shown) and proceed along an upper roller conveyer 44 to an extraction station 48 while a pair of fresh chill moulds are installed in the casting machines at the station 31. The fresh chill moulds are dressed at a station 33 and powdered alloying substance (e.g. FeSi) is added to them at a station 34 from where the chill moulds proceed to the casting station 35. Extracting and treating castings.-At station 48 the chill mould halves are opened by clamp plates 66, 74 (see Fig. 8) by lifting the upper halves 1 in clamp plate 66. A spindle 78 is moved into the bore of each casting 49 and the lower mould halves 2 lowered on clamp plate 74 to leave the castings 49 hanging on the spindles 78. The spindles 78 are retracted to leave the casting 49 laying on an inclined shoot 90. A stop device 95 (not shown) holds the castings while punches 98 (not shown) remove the pricker ends 93 of the castings 49 to a waste shoot 92. The castings 49 are then allowed to roll into a collection bin (91). An operator inserts pricker cores 8 into the empty chill moulds which are closed and sent for re-use along a lower roller conveyer 45 to station 31. Heating moulds.-If a hold-up is encountered during operation chill moulds are carried by a conveyer 100 (Fig. 1) into a holding furnace 99 to maintain their temperature. A grapple 101 lifts the moulds from the roller conveyer 44 to the holding furnace conveyer 100.

Title: A Method and Apparatus for Controlling a Continuous Casting Plant
IPC: B22D11/14
Filed: 1966-12-05
Abstract: 1,173,755. Continuous casting. CONCAST A.G. 5 Dec., 1966 [30 Dec., 1965], No. 54410/66. Heading B3F. In a continuous casting process means is provided for indicating the occurrence and nature of a fault in the process resulting from abnormal casting conditions, i.e. such conditions which are beyond the range of the normal process control means, causing a change in the level of the molten metal in the mould. The casting plant comprises a pouring vessel 1 from which metal is delivered into a feeding vessel 4 which in turn supplies metal at a controllable rate to a cooled curved mould 7. The casing which [emerges from the mould passes through cooling members 9 into a curved guide with rollers 10 and which incorporates further spray-cooling means 11. The continuous withdrawal of the casing 8 is effected by driven rollers 12 and the required lengths of ingot are subsequently cut off by a movable cutting means 17. A fault occurring during the casting operation, i.e. variation in the molten metal supply to the mould or a breakout of metal from the skin of the emerging casting, results in a change in level of the metal in the mould. The change in level produces output signals generated from level indicating means, associated with the mould which initiates through a controller 27 an alarm system and a control to counteract the fault. The level indicating means is in the form of radio-active sensers 45, 48 or electromagnetic wave-transmitting and detecting means 49 to 52 (see Fig. 3). A radio-active monitor 28 in communication with the controller 27 and in response to signals received effects control of a valve 5 for controlling the flow of metal from the vessel 4 to the mould. Further means in the form of a pyrometer 53 or magnetic coil 54 are provided to sense the flow of metal from the feeding vessel 4. Within the cooling region of the members 9 indicating means in the form of temperature-responsive elements 41 or fusible members 42 are provided to indicate a break out of the molten metal core. All the indicating means are interconnected so as to effect control of the speed of the withdrawal rolls and cutting device or the metal feed to the mould in dependence on the fault detected. A time functional relationship between the level indicators in the mould indicates by co-operation with the other indicating means the type of fault occurring. The quantity of molten metal in the feeding vessel is continuously determined by a weighing means 26 on which the vessel is carried. Circuit diagrams for the operation of the system under various fault conditions are shown.
